wire harness problem
 
can u do away with the air intake temp. sensor? I have a 96 ls b18b non vtec swap into my 95 civic my stock engine harness does not have the plug for the air intake sensor what can i do to solve this?

find it cuz u need it! find out the pins at the ecu,(this is ,if you used your stock civic harness) look at the color to see if it in the engine harness ! if not u should at less find the wire in shock tower plugs on the passenger side .. and run your wire from there to the sensors>

Your ECU runs off of a speed-density management strategy, which means it calculates air and fuel based on engine speed and air density. To calculate air density, you either need a MAF sensor or a MAP and intake air temp sensor (and Honda ECUs don't use a MAF obviously).
If you don't have an intake air temp sensor, all you'd be measuring is air pressure, and that doesn't tell you anything about the air density because the density is temperature dependent at any given pressure.

I could have just said no, but I wanted you to know why the answer is no. :D

That plug has to be there somewhere, and if someone has removed it then you need to add it back.

ture, unless he's running alpha-N

Fabrik8 is the man. If I could, I would +rep you.

That's so remote it isn't even worth mentioning.

if he's running ITB's
